Looks very stressed, and the fact it has tankmates is why.
But I assume that's a QT? Looks like a bagarius and a Jaguar cat under those logs :O
It's a pseudopimelodusbufonius an jaguar.
Yeah it's a grow out / Qt tank.
Jag has moved up to the 90 and the cat will be soon.
The convict has moved to.
Possibly try to find her a boyfriend soon then. What are the markers for sexing these pal?
